Answer:
Step-by-step explanation:
Learning task 1 : From the given equation of the line a) find two points that will satisfy the equation, b) the slope and the y intercepts and c) the x and y - intercepts. 1. 3x + 2y = 5 2. 3y - x = 9
Answer:
Step-by-step explanation:
The standard form equation of a straight line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0). Rearrange each equation into this format.
1. 3x + 2y = 5
2y = -3x+5
y = -(3/2)x+(5/2)
a. I'll pick 2 values of x to find 2 values of y:
x y
2 -0.5
5 -5
b. The slope is -(3/2)
c. The y-intercept is (5/2)
2. 3y - x = 9
y = (1/3)x + 3
a. Pick 2 values of x to calculate y:
x y
2 3.67
5 4.67
b. The slope is (1/3)
c. The y-intercept is +3

Answer:
∠ 2 = 26°
Step-by-step explanation:
Since EP is an angle bisector then ∠ 1 = ∠ 2
∠ 2 = [tex]\frac{1}{2}[/tex] ∠ GEF = [tex]\frac{1}{2}[/tex] × 52° = 26°

the number are measurements of radius , diameter, ans circumference of circles A and B. Circle A is smaller than Circle B.
Which number belongs to which quantity? 2.5, 5, 7.6, 15.2, 15.7, 47.7
Step-by-step explanation:
a diameter is always twice the radius.
the only pairs I can see in the list, where one number is twice the other :
2.5 and 5
7.6 and 15.2
so,
2.5 is the radius of A
5 is the diameter of A
7.6 is the radius of B
15.2 is the diameter of B
15.7 is then the circumference of A (as the smaller of the remaining 2 numbers)
47.7 is the circumference of B
we can also check via the formula for circle circumference :
c = 2×pi×r
and yes, the rounded c for r=2.5 is 15.7, and for r=7.6 is 47.7

Mary has a spool of ribbon to make bows. She uses 3 8 yard of the spool's ribbon to make a bow. She has 1 4 yard of the ribbon left on the spool. Which choice is the MOST reasonable tor the yards on the spool before Mary made the bows?
A) 3 8 yard
B) 1 2 yard
C) 5 8 yard
D) 5 6 yard
Answer:
5/8 yards
Step-by-step explanation:
Amount Used: 3/8 yard
Amount Remaining : 1/4
Amount started with = Amount Used + Amount Remaining
We need to find the common denominator for 8 and 4.
3/8 stays 3/8, and 1/4 becomes 2/8 (multiply the numerator and
denominator of 1/4 by 2)
3/8 + 2/8 = 5/8
-Chetan K
Answer:
b) 5/8 yard
Step-by-step explanation:
3/8 of the spool is used to make a bow.
She has 1/4 left. 1/4 = 2/8.
2/8 + 3/8 = 5/8

Jerome bought screen for 59 cents per sq ft. how much did 12 sq ft cost
Answer:
$7.08
Step-by-step explanation:
59 cents = 1 sq ft
? = 12 sq ft
To get from the 1 to the 12 we multiply by 12, so we must do the same to the 59 cents.
0.59 * 12 = 7.08
Therefore, the cost of 12 sq ft is $7.08.

Step-by-step explanation: .__.
Ricky's heartbeat is 70 beat per minute. How many days have elapsed if his
heart beat a total of 504,000?
The number of days passed to have an accumulated heartbeat of 504,000 is the ratio of the total heartbeat and the number of beat per minute ; Hence, the number of days is 5 days
Heart beat rate per minute = 70 beats Total number of beats = 504,000Number of heartbeats per day = 70 × (24 × 60) = 100,800 beats
Number of days = (504,000) ÷ (100,800) = 5days
Therefore, the Number of days elapsed is 5 days.

It takes 80 pounds of seed to completely plant an 11-acre field. How many pounds of seed are needed per acre?
Answer:
Since you're looking for how many acres can be planted per pound of seed, you'd have to divide 9 by 80.
Once divided, you would get 0.1125.
0.1125 ACRES CAN BE PLANTED PER POUND OF SEED.Step-by-step explanation:
A square cake measures 6 units by 6 units by 4 units. The cake falls into a vat of frosting and comes out frosted on all six faces. The cake is then cut up into cubes, each measuring 1 unit on an edge How many of these cubes will have exactly one face frosted?
Answer:
Out of 36 cubes on each face, the 16 cubes not on an edge are the only ones frosted on a single face. 16 on each face x 6 faces = 96 cubes frosted on one face.
Step-by-step explanation:
Hope it helps!
There are 64 cubes that are frosted on one side only.
What is a cube?"A Cube is a solid three-dimensional figure, which has 6 square faces, 8 vertices and 12 edges. It is also said to be a regular hexahedron."
What are 3D shapes?"Shapes in three-dimensions or as we view them in real life are called 3D shapes. Examples of 3D shapes are cubes, cuboids, spheres, cylinders, cones and frustum of cones."
Each face will have three types of cubes on it:
1. Corner Cubes - Frosted on three adjacent sides
2. Edge Cubes - Frosted on two adjacent sides and on the edge between two corner cubes.
3. Central Cubes - Frosted on one side and in the middle of all edges of the face.
Thus, the number of cubes that have only one side as frosted are the total number of central cubes. They can be calculated as follows for all 6 faces:
[tex]Cubes_{central}[/tex] = (6−2)(6−2)+(6−2)(4-2)+(6−2)(4−2)+(6−2)(6−2)+(6−2)(4−2)+(6−2)(4−2)
= [tex]2 (4)^{2}+4(4)(2)[/tex]
= 32+ 32
= 64
Thus there are 64 cubes that are frosted on one side only.

Mario volunteers 1 day each month at the animal shelter. For y days he cleans for 5.5 hours each day. On the other days he walks dogs for 75 minutes.
Part A. Write an expression for the total number of minutes Mario volunteers each year at the animal shelter.
Part B. Simplify the expression.
Enter the correct answers in the boxes.
A. Expression:
B. Simplified form:
Part A: The expression for the total number of minutes Mario volunteers each year at the animal shelter = (405/y) x 365
Part B: The simplified form of the expression for the total number of minutes Mario volunteers each year at the animal shelter = (147825/y) minutes
Number of days Mario volunteers each month at the animal shelter = 1
Number of hours Mario cleans for y days = 5.5 hours
Number of hours Mario each day = 5.5/y
Number of minutes Mario uses to walk dogs for y days = 75 minutes
Number of hours Mario uses to walk dogs for y days= 75/60
Number of hours Mario uses to walk dogs for y days= 1.25 hours
Number of hours Mario uses to walk dogs each day= 1.25/y
Total number of hours Mario volunteers in a day = Number of hours Mario cleans each day + Number of hours Mario uses to walk dogs
Total number of hours Mario volunteers in a day = 5.5/y + 1.25/y
Total number of hours Mario volunteers in a day = 6.75/y
Convert the number of hours to minutes
1 hour = 60 minutes
Total number of minutes Mario volunteers in a day = (6.75/y) x 60
Total number of minutes Mario volunteers in a day = (405/y) minutes
Number of days in 1 year = 365
The expression for the total number of minutes Mario volunteers each year at the animal shelter = (405/y) x 365
The simplified form of the expression for the total number of minutes Mario volunteers each year at the animal shelter = (147825/y) minutes

Here are two points from line AB: A (9,-2) B(1, 14) Here are two points from line CD: C (6.-10) D (8,-14) Are these lines parallel, perpendicular or neither?
Step-by-step explanation:
slope of AB = y2 -y1/x2 -x1 =14 -(-2)/1-9
= 14 +2 /1 -9
= 16/-8
= -2
slope of CD = -14 -(-10)/8 -6 = -14 +10 /2
-4/2 = -2
since slope of AB = CD
(The lines are parallel to each other)
